The invention discloses a combined circulating refrigeration system suitable for an all-electric aircraft and a working method of the combined circulating refrigeration system, belongs to the field of all-electric aircraft environment control, and meets all-electric aircraft environment control requirements in multiple aspects. The system is driven by airborne electric energy and is formed by combining a steam compression refrigeration cycle, an air expansion refrigeration cycle and a liquid cooling cycle, and an airborne motor is used for driving the steam compression refrigeration cycle to replace stamping gas to serve as a cold source; meanwhile, an electric air compressor is used for compressing external environment air to serve as a high-pressure air source needed by air expansion refrigeration circulation; liquid cooling circulation and air expansion refrigeration circulation are adopted for cooling adjustment of the equipment cabin and the cabin, meanwhile, cabin return air and external environment entrained air are mixed to participate in air expansion refrigeration to form closed circulation, and the air entraining amount requirement is effectively reduced.

    本发明公开了一种适用于全电飞机的组合式循环制冷系统及其工作方法,属于全电飞机环境控制领域,多方面满足了全电飞机环境控制需求。本发明系统受机载电能驱动,由蒸气压缩制冷循环、空气膨胀制冷循环和液体冷却循环组合而成,利用机载电机驱动蒸气压缩制冷循环替代冲压气体作为冷源,同时利用电动压气机压缩外界环境空气作为空气膨胀制冷循环所需的高压气源;分别采用液体冷却循环和空气膨胀制冷循环对设备舱和座舱进行冷却调节,同时采用座舱回风与外界环境引气混合参与空气膨胀制冷形成闭式循环,有效减少了引气量需求。
